OTFE (on-the-fly-encryption) with Syncplify.me MFT!

We’ve just added a MAJOR feature to Syncplify.me MFT! (not abailable in the Alpha-1 download yet, it’ll be in Alpha-2): OTFE, which is short for on-the-fly-encryption.

Basically, when OTFE is enabled, Syncplify.me MFT! encrypts files as they are uploaded to a remote file server (SFTP, FTP, S3, whatever, …) and decrypts them as they are downloaded back to the local machine.

This encryption/decryption happens on-the-fly, directly on the uploaded/downloaded data stream, so it doesn’t need to use temporary files on your disk; the entire process is very memory-friendly, because it encrypts/decrypts small buffers as they are transferred.

Here’s an example script that adds OTFE to file transfers:

{
	ConsoleFeedback = true;
	var scli = NewSftpClient();
	scli.Host = 'sftp.server.com:22';
	scli.User = 'your_username';
	scli.PassFromSecret = 'secret containing the password';

	// OTFE options
	scli.Options.OTFE = true;
	scli.Options.OTFEKeyFromSecret = 'key secret name';
		
	if (scli.Connect()) {
		// Files transparently and automatically encrypted during upload
		scli.UploadR('./_dload/*.txt', '/testmft');
		// Files transparently and automatically decrypted during download
		scli.DownloadR('/testmft/*.txt', './_dload/dec');
		scli.Close();
	}
	scli = null
}
